Yes. IVF allows sperm to fertilize the egg naturally, while ICSI involves injecting a single sperm directly into the egg.

What It Is, When It Is Needed & How It Works
ICSI (Intracytoplasmic Sperm Injection) is an advanced IVF technique where a single healthy sperm is directly injected into an egg to achieve fertilization.
It is used when natural fertilization is difficult, especially in cases of male infertility or previous IVF failure, significantly improving fertilization chances.
- Personalized treatment
- Ethical guidance
Why is ICSI Needed?
ICSI is recommended when fertilization may not happen naturally. Even when reports appear normal, fertilization may still fail - this is where ICSI becomes critical.
Clinical Perspective
In real clinical practice, male infertility is often underestimated.
Many couples come with “near-normal” reports but still experience failed fertilization in IVF cycles. This is because standard semen analysis does not always reflect sperm function at the microscopic level.
At MIRA IVF Centre, the decision to perform ICSI is not routine - it is strategic and individualized.
- Borderline semen - high risk of fertilization failure
- Repeated IVF failures - ICSI may be crucial
- Lab quality and embryologist expertise directly impact outcomes
“ICSI is not just a technique - it is a decision that can change the outcome of an IVF cycle.”
Evidence (What Science Says)
- ICSI significantly improves fertilization rates in male factor infertility.
- It is widely used across advanced IVF laboratories worldwide.
- Recommended in cases of poor sperm parameters and previous fertilization failure.
However:
ICSI should be used judiciously - unnecessary use does not improve outcomes in all patients. Correct case selection is critical, and lab expertise plays a major role.
Step-by-Step ICSI Process
Each step requires precision, timing, and expert decision-making to ensure the highest chances of success.
Fertility Evaluation
Hormonal tests, ultrasound, and semen analysis
Ovarian Stimulation
Controlled stimulation to develop multiple eggs
Egg Retrieval (OPU)
Minor procedure under sedation
Sperm Selection
Best quality sperm selected under microscope
ICSI Procedure
Single sperm injected directly into each egg
Embryo Development
Fertilized eggs develop into embryos
Embryo Transfer
Best embryo placed into uterus

Frequently Asked Questions
Find answers to common questions about the ICSI procedure.
No. The ICSI procedure is performed in the laboratory. Egg retrieval is done under sedation, so it is comfortable.
Success depends on age, egg quality, and embryo development, but ICSI improves fertilization rates significantly in male factor infertility.
It is recommended in cases of low sperm count, poor motility, abnormal morphology, or previous IVF fertilization failure.
Yes. Even very few sperms can be used effectively in ICSI to achieve fertilization.
ICSI is widely used and considered safe, though proper case selection and counseling are important.
Embryologists select the best available sperm under high magnification based on movement and structure.
